1 RIJEKA AGGLOMERATION Improvement of Water and Wastewater Infrastructure

2 PROJECT LOCATION

3 RIJEKA THE CITY ON WATER Water supply and wastewater collection system of Rijeka and surrounding area is considered to be one of the most complex systems in the Republic of Croatia

4 Agglomerations AGGLOMERATION KLANA Municipality of Klana Water supply area: 517 km 2 Number of inhabitants: AGGLOMERATION RIJEKA Cities of Rijeka and Kastav Municipalities of Viškovo, Čavle and Jelenje AGGLOMERATION BAKAR-KOSTRENA City of Bakar Municipality of Kostrena AGGLOMERATION KRALJEVICA City of Kraljevica

5 AGGLOMERATION RIJEKA PROJECT PREPARATION Preparation of the study-project documentation (started in 2010.) Feasibility study and the project application Jaspers issued The Completion note for the project Environmental Impact Assessment of Wastewater collection system Decision on acceptability issued by Ministry of Environment and Energy Conceptual design and main design for reconstruction, upgrade and extension of wastewater collection system on the territory of the agglomeration Rijeka In the final phase of obtaining remaining building permits (out of the 118 projects, 96% permits were obtained) Property-legal preparation Solving land ownership issues for almost 4000 building plots Project documentation preparation Preparing the project documentation for the WWTP and sewage system construction, works supervision, equipment procurement, informing and visibility, project management service expected in the second half of 2018.

6 Project activities Agglomeration Rijeka project description Construction of transport pipelines and optimization of existing sewage system 33,4 km and 53 accompanying objects Extension of wastewater collection network 184,1 km and 108 accompanying objects Reconstruction of parts of the water supply system 100 km Construction of the WWTP Rijeka capacity PE (population equivalent) with secondary treatment (biological stage) Other activities related to construction of sewage system Equpiment procurement Works supervision for sewage installation WWTP construction supervision Visibility and informing Project management

10 PRESENTATION OF CONSTRUCTION PHASES Legend: phase 0 phase 1 phase 2 phase 3

11 RIJEKA GATEWAY PROJECT Existing conditions Delta South The Urban Renewal of the Delta area Delta area located in the town center planned content: main town park, corridor of the main town road and the town railway through Delta, mixed use area (modern nautical and passenger terminal for accepting ferry boats and cruisers, different commercial, business, cultural and public events), utility and service use area for WWTP location

12 NEW WASTEWATER TREATMENT PLANT OF AGGLOMERATION RIJEKA NEW WWTP EXISTING WWTP

13 The land on which has been planned to build WWTP Rijeka -> situated on cadastral plots in proprerty of the Republic of Croatia WWTP Rijeka -> defined by the Spatial Plan of the Primorsko-goranska region and the Spatial plan of the City of Rijeka and the Spatial Plan of the Primorje-Gorski kotar County Urbanistic solution of WWTP > defined by Rijeka Gateway Project General information Type of the contract: FIDIC YELLOW BOOK Expected contracting works - > end of WWTP capacity: PE 1 year for design, 2 years for construction and 1 year for WWTP test work WWTP type: SECONDARY TREATMENT Estimated deadline for design: Estimated deadline for construction and test work: end of Existing WWTP (mechanical pretreatment) will be removed form the location Required surface: m² Surface defined as maritime domain (embankment) SLUDGE MANAGEMENT Absence of Sewage Sludge Directive in the Republic of Croatia Treated sewage sludge from WWTP Rijeka will be transported to the HOLCIM Hrvatska d.o.o. Koromačno

14 WASTEWATER TREATMENT PLANT OF AGGLOMERATION RIJEKA VISUALIZATION ACCORDING TO THE CONCEPTUAL DESIGN New WWTP

15 BENEFITS OF EU PROJECT: Compliance with the Urban Wastewater Treatment Directive Grants in the amount of 1,25 billion HRK Higher utility standard Clean environment and protected drinking water Reduced losses and improved efficiency of the water supply system Existing connection rate 68 % SITUATION AFTER EU PROJECT Connection to the public sewer system for approx. 92% of population
